In order to illustrate the applcatonof my in- 45 1. -Alplastic iioor comprising iibrous blocks, vention, I have in Fig. 1 illustrated'a part of. a spaced to" provide plastic 1 receiving VChannels plastic cor' which maybe composed of concrete therebetween, the 'lower'side and end edges ofV and construction elements,- made in .accordance each block being undercut to provide grooves, and with the teaching -ofethis 1 invention, hereinafter fibrous iniexble slabs mounted in said grooves to -mere fully described,` 'The floor also meludes 5o provide amoistnre-proof joint between the lower beams E of standard construction, adapted to facesof adjacentbloeks at the bottom of each support the oor ina well-known manner. ohannel.

The hoor of this invention includes parallelly 2- A ploso floor Comprising parallelly 211- arranged fibrous blocks 'Lithe lower face of each ranged fibrous blocks spaced to provide Plastic .of which is provided with amarginalgroovethe o@ receiving spaces, therebetween, the bottom faces of the blocks beinfg` undercut to provide marginal grooves, and fibrous soit pieces engageable in said grooves to prevent plastic seepage between and below the blocks.

3. Floors for buildings including ber blocks aligned in rows, the latter being spaced to provide plastic receiving channels, sealing means in the bottom of each channel comprising a soit member arranged between the lower adjacent faces of the blocks. said lower adjacent faces being grooved to interft the soit members and prevent passage of the plastic materials through the bottom face of the door.

4. A concrete oor including parallelly arranged beams, parallelly arranged brous blocks positioned between said beams and spaced to provide concrete receiving channels between the ysides of the blocks and between the ends of the blocks and said beams, and soflit members engaged with said beams and intertting the lower margins of the blocks to provide overlapped joints between the blocks and soiiit members.

5. A plastic floor comprising parallelly arranged brous blocks spaced to provide plastic receiving spaces therebetween, the bottom faces of the blocks being undercut at their margins to provide a. groove 'in each of the lower edges of the block with an overhanging abrupt shoulder, and brous iniiexible somt pieces engaged in said grooves and abutting the shoulders thereof to form a liquid seal between the blocks and sot pieces.
